Chinese patent medicines without specified production dates and expiration dates are considered counterfeit and inferior drugs, and should not be taken. Additionally, improper storage and handling of Chinese patent medicines can also lead to loss of efficacy or increased toxicity, among other issues. The following should be noted:
(1) Tablets - Tablets are generally smooth and hard, and not easily broken. If the surface of the tablet is hairy, discolored, loose, sticking to other tablets, or has insects or mold, it should be discarded and not used.
(2) Granules (Powders for dissolving) - Chinese patent granules (powders for dissolving) are often flavored and may contain sugar. Good-quality granules are dry, free of lumps, insects, and mold. Spoiled granules may become moist, clump together, or emit a moldy odor.
(3) Honey Pills - This is a traditional dosage form for Chinese patent medicines, usually wrapped in aluminum-plastic or thick wax shells. High-quality honey pills should have undamaged aluminum-plastic or wax shells, consistent color and luster, and no insects, hair, moldy smell, or acidic odor. If not, it indicates spoilage or possible contamination and should not be taken.
